So, I am in dire need of some special voices for a mock advertisement, but I don't really have access to voice actors and I am awful. I have seen people use text to speech software that has good natural inflections and record features. Any suggestions on what software I may be able to get to do this?

I came across a really good T2S. Listen to this demo track I made, at the beginning and the end you will hear the voice i generated. I promise you it isnt a real vocal, its emulated.

On the website www.naturalreaders.com, i used the 'try it' box to generate the vocal. It will take a lot of playing around and you will have to record the output of the browser into recording software. But My god it provides astonishing result as you will hear in the composition i linked.
